Original application filed March. 25,

To-all'wwmz'tmay concern.' Be it known that I,. ALBERT KINGSBURY, a citizen of the United States of America,

and a resident of Pittsburgh, Allegheny have incounty, and State of-Pennsylvania lmprovef vented certain new and useful ments in ThrustBearings, of which the following is a specication reference being had to the accompanying drawings, forming a part thereof..

My invention relates to bearings and particularly to thrust bearings which embody segmental bearing shoes or members adapted to tilt in response to the wedging action of the oi-l when the bearing is .in service. This application isa division of my coarch 2 5, 1916, for thrust bearings. An object of my invention is to provide a bearing, such as a thrust bearing, with an annularly arranged plurality or set of bear- 'lar with whichA the ing segments and means tiltable about'. a single axisffor equitably distributing the bearing pressure thereon.

Another object ofimy invention is'to provide a. bearing with an annular equalizing member which vis adapted'to'tilt about a sin`' gle axis and a plurality of bearing segments or shoes so mounted `Onsa-idmember that the .bearing vpressure on said segments 1s` equitably distributed by said member.

' Anotherobject of my invention is to proing .segments or shoes mounted thereon vto tilt, preferably both' circumferentially or tangentia'lly and radially of the bearing.

Another obj ect of my invention is the pr'oduction of a very .simple and easily constructed bearing of the aforesaid character and vary by a considerable amount in relalvide -a bearing with an annularv equalizing j ymember as aforesaid and a plurality of bear-v tive thickness; "and notwithstanding any in-f accuracies in the Ioriginal fitting', or greatly unequal wear in use, cr-.the heatingeffects arisingduring normal operation which are likely to crown the surface of the thrust col-Y f segments or shoes (3ooperate.

Another object of my invention is to provide va bearingfcomprising a pair of bearing shoes disposed on oppositel sides of the aids purpose.

Other. objects and advantages of my in-i' vention will be set forth hereinafter, and in order that my invention'may be thoroughly understood I will now proceed to describe the sa'me in the following speeilication, and then point out thenovel features thereof in appended.. claims. r

The invention is capable of receiving a 'variety of mechanicalexpressions one ofA which is shown von the accompanying drawings, but it is to be expressly understood that the drawmgs are for purposes of illustration only and are not to be construed as a denition of the limits ofthe invention, reference being had lto the vappended claims for that means, is a thrust collar 13 havingl a 'bearing .and the thrust collar 13 coperates With a plurality iof bearing segments orshoes 17,

Said member 2()` has diametlicallyfopposed rocking or knife-edge supportsy 211 that engage saidfbase- 16 between the projections 19, and apairv of upwardly extendlngspherically .faced .projections 21 locatedgon opposite sides ofthe axis of the bearingandon opposite sidesrof the .tilting axisof'themernber 20, the line of the projections 21, inthe elnbodimentshown, being at right angles to the axis of the rocking supports 24:."

The bearing shoes or'seginental members -17 are mounted to tilt both ci'rcumferentially.

and radially of the bearing on the-projec'd tions 21 and are heldin .place by an annular .guide 22 which is provided With projections 23.
